The symbol shows the location of the Emley Moor (Kirklees, England) transmitter which serves 1,550,000 homes. The bright green areas shown where the signal from this transmitter is strong, dark green areas are poorer signals. Those parts shown in yellow may have interference on the same frequency from other masts.

steve: Only over the last few months has Digital Mobile Spectrum Limited ("at800") conducted some tests to get a more accurate handle on the likelihood of issues. This can only ever be a probability based on a statistical sample (i.e. a test).
The only "con" on the population in general can be via information published by the media.
When the media asked - before tests were carried out - how many homes might be affected then the only possible answers that the powers that be could give were:
1. the estimated figure having not carried out a real-world test, or;
2. "we don't have a figure".
Can you imagine how it would have been spun in the news if they had answered with the latter? The newspapers wouldn't have been likely not to run a story if that answer were given. And so they would have publicised the fact that there was no official estimate.
Therefore the only likely out was as happened which is that the best guess at the time was used. It turns out that, following the tests, less homes will be affected, so the estimated figure is now lower than it was.
Can you imagine how it would look if the found that the issue is likely to affect far more people than first thought? The figure would have to have been increased which wouldn't look good.

If you are using a communal aerial system then it is the responsibility of your landlord, or whatever party maintains the system, to install any necessary filter. It could potentially already be fitted with a filter anyway.

Briantist: I mentioned it as it would seem logical to suggest it because a wideband aerial may have more gain on C61 to C69 than an equivalent Group B aerial. Perhaps in practice any difference is neglible and there are far more bigger factors in play such as field strength.

Does not bode well it would seem, I live in North Leeds and can only get freeview from Emley moor with an aerial transformer thingy in the loft and signal booster. Analogue was difficult as well before digital and we have very high aerial poles built on the sides of the house to get a signal at all.
I am only 1/5th of a mile from the main transmitters of all the main mobile companies so may have problems as they are on top of local high rise flats grouped together and have very high output, The signal has always been poor in Leeds 6 which covers Headingley and its large population although some areas are better than others.

steve: The terrain plot suggests that you may have line-of-sight to the top of the Emley Moor tower, not taking into account anything on the ground. I noticed the high-rise flats that will be in the way for some in your general area.
With this in mind perhaps the tall aerial poles are not because the signal is weak but because those buildings reflect the signals (because they are so strong). In the days of analogue this would have resulted in ghosting, but with digital it isn't really an issue.
If this is a communal aerial which feeds multiple flats then it will likely have an amplifier (booster) because splitting the signal will result in less signal to each output. Therefore the objective of the amplifier is to counteract the loss due to splitting it.
As I say, if it's a communal system it may already be filtered or the party responsible may have to arrange for a filter to be fitted. It will not require each tennant to use there own filter as the filter, in a communal system, should be fitted at the aerial end.

In addition to all this.
The LTE (at the wall plate) strength needs to be at least 10 - 20db above the signal strength.

Dave Lindsay / Steve: As I see it from my point of view although a group B aerial (Ch's 35-53) would under "normal" circumstances be a far safer bet for the reception of Emley Moor (Channel span Ch41-Ch52) in cases where the possibility of 4G interference was a definite issue, the slight deficiency that most aerials have on the last few channels at each end of their coverage range being in this case a plus point rather than normally the reverse, and indeed the protection afforded by using an aerial with a restricted top end coverage could even be further reinforced by fitting a 4G filter as well.
However the reason I said "normal" circumstances is because the set up as described would only be satisfactory in cases where it was previously determined that a reasonably strong signal was being received on the high channels before any alterations were made otherwise the COM channels will be difficult to receive, and so everything hinges on what like Steve's reception is (signal / quality strength wise) on Ch52 / Ch51 / Ch48 and whether or not they can stand a slight reduction in signal strength, which of course they invariably would do using the aforementioned set up.

I know there is no reports of any engineering works on this transmitter But has anyone else noticed recently, more so at night a big drop in the signal levels? the BBC multiplex signal quality here at one point tonight was none existent. The Itv one has only in the last hour gone back to its normal levels for here in the last hour. Its happened a couple of times this week and was jusy curious to know if anyone else has noticed it? Postcode WN2 1sz. And yes i know my local transmitter is Winter hill.

michael : I should think that the answer is to do with the fact that you don't have line-of-sight due to the Pennines being in the way!
The high ground over which you are receiving is likely to form a mist at night, which might be the cause.
Refer to the terrain plot:
Terrain between ( m a.g.l.) and (antenna m a.g.l.) - Optimising UK DTT Freeview and Radio aerial location
How do you fair in autumn, winter and spring? I think that it's quite likely to be misty up there quite a bit of the time.

Hi Dave thanks for your response and yeah I would fully expect that, if that had always been the case but it has only started in the last week or so and I have lived here for 3 years now and apart from known engineering works it has been fine. (53.5454,-2.6375)

michael: I'm surprised you have got it so reliably.
We don't know for certain, but it would seem sensible to think is that Emley Moor doesn't put out as much signal in a westerly direction as other directions, as it will be being beamed into the Pennines, or else be available, possibly intermittently on the "wrong" side of the Pennines.
Parbold relay is co-channel with Emley's PSBs, albeit vertically polarised.
